Interjet has filed an application to the US Department of Transportation to perform scheduled service from Mexico City, Guadalajara and San Jose del Cabo to Santa Ana, California.
The Mexican low-cost carrier says it plans to start the flights on or about 14 September pending US approval.
Interjet has also requested authorisation to perform service from Toluca to Las Vegas, Houston and Chicago.
Interjet chief executive Jose Luis Garza told Flightglobal earlier this month that he was confident the carrier could start service from Guadalajara and Mexico City to Southern California by the end of 2012. At that time, he said that the airline was weighing the pros and cons of choosing among airports in Santa Ana, San Bernardino and Ontario, California.
The airline received a designation from the Mexican government on 30 March to perform service from Mexico City to Santa Ana, as well as routes from Toluca to Las Vegas, Houston and Chicago. It received a similar designation on 30 July for the routes from Guadalajara and San Jose del Cabo to Santa Ana on 30 July.
Interjet started transborder flying in December 2011 when it initiated service between Mexico City and San Antonio. It then expanded its network to include routes from Mexico City to Miami and, as of 2 August, New York.
